Serika is taken by the strange man she meets, Takuru, into the school basement. Takuru says that he has an important task to do there, but he's reluctant to take her along at all...
And that's how we would 
live our lives together.
وهكذا سنعيشُ حياتَنا معاً

Así es como viviremos juntos.
C’est ainsi que l’on vivra ensemble,
tous les deux.
E in questo modo
E era assim que viveríamos nossas vidas juntos.
